I don't think you can quantify how dangerous people think it is. Certainly I don't believe you know how dangerous I think it is.
My points are simply that: you cannot derive a conclusion about the danger of fallout from the large number of nuclear tests that have occured, since the majority of those tests were underground and many of those that weren't were of relatively modest yield; and that the real danger of fallout was significant enough to bring arch foes to the negotiating table during the height of the Cold War. I'm sure their respective nuclear scientists were well aware of the real dangers.
